intelligent water meters need to recharge to buy a drink to use, after buying water on the meter inserted IC card, to water. However, in the use of the process, because of forgetting to replace the battery, many users found that the insertion of IC card, LCD screen has not shown the number, at this time will occur two kinds of possible problems, one is inserted card, water meter does not show the number, but the supply of normal tap. There will also be a situation, that is, immediately water. What are the reasons for these two different situations? This is because the IC card water meter/intelligent water meter motherboard battery and panel battery is different, if the LCD is not displayed, and will not affect the user normal water, at this time the user should replace the battery as soon as possible. And if the real water supply in the home, then there is almost only one reason, that is, intelligent meter monitoring to run out, automatic to the brake plate issued a signal.

For a long time, the water meters are usually installed outside of the South, some mounted on the wall of the building, installation of water meter hole in the ground, has no uniform standard for the installation. Groundwater table covers are lighter can not withstand the vehicle rolled erosion, much less tolerate cold weather test, especially in recent years, the La Nina weather phenomenon, resulting in Jiangnan region temperature normal cool, frequent water frost damage.

Water meter installed taking into account safety and convenience, should not be installed in sensitive to freezing and exposure conditions, should be installed in a closed solid, dry-and sediment pollution, prevent water erosion-proof vehicles rolling sites, so as to further improve the quality of water services, resolving the contradiction between water supply and charges, avoiding unnecessary waste.

Therefore, the unified houses under construction when a water meter installation environment, relevant departments as soon as possible a clear design standards, introduction of specification for installation of House in a well designed and built a margin for piping or equipment. Water meter installation planning for routine inspection and maintenance, as well as frost damage and facilitate unified meter reading and management. Existing and underground water meters will be installed on the wall reinforcement and protection work, add strong durable wall water meter protection box, reinforced surface water table covers, in cold weather before the water companies should unify the bandage cold warm outdoor water meter equipment, increase the security level.
Remote water meter installation, to pay attention to these matters. Such as winter frost, best signal transmission area can open, and user-friendly as possible and water Division.
